Professional Applications & Engineering Value
This M4 nylon plastic flat head screw is engineered to address common challenges in industrial assembly, such as galvanic corrosion and electrical conductivity. The nylon material provides inherent resistance to moisture, chemicals, and rust, making it a superior choice for electrical enclosures, automotive components, and outdoor equipment where metal fasteners would fail. Its fully threaded metric coarse thread with a 0.7mm pitch ensures quick installation and high pull-out strength, reducing assembly time and improving joint integrity. The flat head with slotted drive allows for flush mounting in countersunk holes, maintaining a smooth surface profile. By meeting ASME B18.6.7M standards, these screws deliver consistent dimensional accuracy, ensuring reliable performance in precision engineering applications and reducing the risk of thread stripping or misalignment.
Specification Summary & Compliance
This fastener features a Metric M4 x 0.7mm thread with Class 6g tolerance, ensuring precise fit and interchangeability. It is fully threaded, right-hand direction, with a standard 90° countersink angle. Manufactured in compliance with ASME B18.6.7M for dimensional consistency, and certified RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, confirming the absence of hazardous substances and adherence to environmental regulations.
